DEMOUNTABLE RIM.

Specification of Letters Patent.

Patented Aug. 1 1916.

Application filed March 17, 1914, Serial No. 825,389. Renewed April 29, 1916. Serial No. 94,509.

To all whom it may concern:

1 Be it known that l, HENRY J. TRAnns, a citizen or the United States, and resident of ltdwardsville, Madison county, Illinois, have invented certain new ahduseful Improvements in Demountable Rims, of which a full, clear, and exact description, reference being had to the accompanying drawings, foaming a part hereof.

itly invention relates to improvements in dcmountable rims, and the object of my invention is to construct a felly band which is arranged to be permanently secured to the folly and isprovided with annular inclined shoulders and segmental channels arranged to receive locking pins on a run, the ends of said channels being'im.

fzlllliifl or chamfered in directions which will bring said rim to frictionally engage'with said shoulders, and a removable lot-king device to. prevent relative rotation of the rim andfelly band, the one flange of the rim being removable in order to perini'tthe detaching of the tire, said removable flange being provided with pins substantially of the same design as is carried by the rim for engagement with the telly band,

lid

littl till whereby said flange may be quickly and easily removed for thedetachment of the tire or the rim removed, as is common with demountable rims.

With the above purposes in view, my invention consists'in certain novel features of construction and arrangement of parts as will. behereinafter more fully described, pointed out in the claim and illustrated in the accompanying drawings, in Which Figure 1 is a fragmental elevation of a wheel constructed according to my inven:

tion, a portion of the folly being shown in section; Fig. 21s an enlarged transverse sectional elevation taken through a folly, felly band, the separable rim and a pneumatic tire; Fig. 3 is an elevation on a reduced scale, showing my improved rim; Fig. 1 is an elevation on a reduced scale, showing my. improved detachable rim flange; Fig. 5 is a fragmental plan, showing the chamfered ends and stops in the channeled rim flange; Eig. 6 1s a iragmental sectional elevation showing means forqsecuring the rim flange against rotary movement relative to the rim;-Fig. 7 is a fragmental elevation showing the means for securing the run against rotation relative to the folly band; and Fig.

8 is a fragmental plan illustrating theremovable plate which covers the slot in the fell y and band and the valve cap for holding said plate.

Referring by numeralsto the accompanying drawings: lOdesignates a felly, which may be of any desired construction.

11 designates a felly'band, which is arranged to be permanently secured in any desired manner to the peripheral face of tho.

felly band. On the periphery of said band of the insertion of the projections 16 carried by the rim. The walls of the depression 14 on either side of the slots 17 are inclined. so thatwhcn the said projections engage said inclined faces, there will be a tendency to move the rim against the in clined shoulders 12 and 13. This construction is in all particulars like therim and.

rim flange shown in Fig. 5.

18 designates an inclined shoulder on the inner perimeter of the rim at the outside margin thereof, which engages against the shoulder 13, while at the inner margin of the rim opposite the shoulder 18 there is an inclined shoulder 19 formed by chamfcring or beveling the rim to fit against the in clined shoulder 12.

, 2021 designate depressions formed in the inner perimeter of the rim and the pcripheral face of the felly band to receive a key 22 which prevents relative rotation between the rim and folly band. This key 22 is preferably secured to the folly by means of a bolt 23, and said key carries a hook 2 1 which facilitates its removal when the bolt'is loosened. n

The rim 15 has at its inside margin the usual flange 25, which is preferably foru-zcd integral with the rim. and whose cross section may vaiyaccording to the type of tire,

to he used therewith. 26 designates an integral extension of the as clearly shown in Fig.

rim proper at its outside margin, which extension has its outer peripheral face,

"shown in Fig. 2, beneath the inner peripheral face of the rim,

of the flange to's aid channel, and the outer wall next adjacent said slots is provided with inclined. faces 32 and the'fixed stops 33, so that when the pins 28 are brought to engage with either of the inclined faces 32 there will, be a tendency toward the crowding of the flange against the tire and also against the inclined shoulder 27. The channel 30 is interrupted at one point by a bridging lug 34 and the extension 26 of the rim is. provided with spaced apart internally threaded seats 35 at points adjacent the lug 34. to receive a set screw 36 which when placed in position will engage the lug 3-1 to prevent rotation of the flange relative to the rim in one direction, while the pin 28 will engage with one or the other of the stops 33 and prevent rotation of the flange relative to the rim in the other direction.

In order to provide for the rotation of the rim relative to the telly band, the telly band, as well as the telly, is slotted at 37, l, and through the inclined faces 32 at each side of the slots 31, the rim may be or left hand wheel.

Formed in the outside margin of the removable rim flange 29- are the diametrically used for either a right opposite seats 41, in order that a tool in the form of a bar may be placed insaid seats to rotate the rim flange relative to the rim as required in putting on or taking oil" a tire.

I claim:

In combination with a felly band having on its perhphery spaced annular shoulders of different inclinations, the outermost shoulder having openings therethrough and which openings are chamfered at their inner ends, a rim having on its inner perimeter spaced annular shoulders inclinedvto correspond with the shoplders of the telly band, projections on said rim for insertion through said openings and to engage said chamfered inner ends thereof and means to prevent relative rotation of the rim and felly band.

In testimony' whereof, I have signed my name to this sp;-3ificati0n, in presence of two subscribing witnesses.
